Problem is that the amount of energy storage we need to convert 100% to renewables is enormous. Pumped hydro works just fine but takes a massive amount of area and the right topography. Compressed underground air storage also works, but is geology-specific.
The right answer is a blend of wind, solar, and nuclear fission, but there's still a ton of (mostly ignorant) folks against nuclear power.
